Solve for b. r=7(b+a)

To solve for b, we need to isolate b on one side of the equation.

Given: r = 7(b + a)

First, distribute 7 to both terms inside the parentheses:

r = 7b + 7a

Next, subtract 7a from both sides to isolate 7b:

r - 7a = 7b

Finally, divide both sides by 7 to solve for b:

b = (r - 7a) / 7

Therefore, the solution for b is:

b = (r - 7a) / 7

Solve for y.
C = (y+k)h

To solve for y in the given equation C = (y + k)h, we need to isolate y on one side of the equation.

Given: C = (y + k)h

First, divide both sides of the equation by h to isolate y:

C/h = y + k

Next, subtract k from both sides:

C/h - k = y

Therefore, the solution for y is:

y = C/h - k

Solve for x.
2(x - 1) = z

To solve for x in the equation 2(x - 1) = z, we need to isolate x on one side of the equation.

Given: 2(x - 1) = z

First, distribute 2 to both terms inside the parentheses:

2x - 2 = z

Next, add 2 to both sides to isolate 2x:

2x = z + 2

Divide both sides by 2 to solve for x:

x = (z + 2) / 2

Therefore, the solution for x is:

x = (z + 2) / 2

Solve for b.
r = (6 + b) * m

To solve for b in the equation r = (6 + b) * m, we need to isolate b on one side of the equation.

Given: r = (6 + b) * m

First, distribute m to both terms inside the parentheses:

r = 6m + bm

Next, subtract 6m from both sides to isolate bm:

r - 6m = bm

Finally, divide both sides by m to solve for b:

b = (r - 6m) / m

Therefore, the solution for b is:

b = (r - 6m) / m
