The solution of an equation is the value of the variable that makes the equation true. To find the solution of each equation, we isolate the variable by performing the same operation on both sides of the equation.
A. x + 19 = -5
Subtract 19 from both sides:
x = -5 - 19
x = -24
B. x - 7 = 28
Add 7 to both sides:
x = 28 + 7
x = 35
C. x - 7 = 28 (same equation as B)
The equation is the same as B, so the solution is also x = 35.
D. x + 25 = 2
Subtract 25 from both sides:
x = 2 - 25
x = -23
Out of the given equations, the solution with the lowest value is D. x + 25 = 2, which has a solution of x = -23.
Which of the following has the solution of the lowest value
A. x + 19 = -5
B. x - 7 = 28
C. x - 7 = 28
D. x + 25 = 2
