Question

Given the equation 3x + 25 = 7x − 5, which order of operations completely solves for x?
A.) Add 3x, then subtract 25, lastly divide by 10
B.) Subtract 3x, then add 5, lastly divide by 4
C.) Add 7x, then add 25, lastly divide by 10
D.) Subtract 7x, then add 5, lastly divide by 10

Answer 1

since we need to isolate x
we bring all the x terms on one side

for that we need to subtract 3x from both sides
so that it goes from left side to right side

so subtract 3x from both sides in 3x+25 = 7x-5
