To solve for y in the equation 2 x + y = 5, subtract 2 from both sides of the equation.
2 answers:
Answer:
False
Step-by-step explanation:
To solve this equation 2x + y = 5, you need another pair equation with the same variables, or one of the variables (x or y) need to be known to solve this equation.
Or you need to subtract 2x from both side to make y subject of formula.
Answer:
False.
Step-by-step explanation:
Because we have to isolate y and subtracting 2 will not put y alone on one side.
We have to subtract 2x in order to solve for y.

Answer:
A
Step-by-step explanation:
Given
5(x - 7) = 55, then using the distributive property, that is
a(b - c) = ab - ac, then
5x - 35 = 55
