Not quite sure, can’t see the picture
X+7>_12 is the correct answer because 7+5 is 12 and the equation is saying that 12 is equal to 12 which is true
So (x + 5)*3 - 15 = 42
so the answer is
42 + 15 = 15 + 3x
so solving for x:
x = 14
Isolate the variable by dividing each side by factors that don't contain the variable.
