Question

6x-y=-4 2x+2y=15 substitution method

Answer 1

First, solve for y in the first equation:

6x - y = -4
y = 6x + 4

Next, substitute this expression for y into the second equation:

2x + 2(6x + 4) = 15
2x + 12x + 8 = 15
14x + 8 = 15
14x = 7
x = 0.5

Now, substitute this value of x back into the first equation to solve for y:

6(0.5) - y = -4
3 - y = -4
y = 7

Therefore, the solution to the system of equations is x = 0.5 and y = 7.
