Question

Write an equation and solve: Twice a number, increased by 3 is 7.

A) 2
B) 5
C) 8
Eliminate
D) 20

Answer 1

'number' will be x
2x+3=7
subtract 3 on both sides:
2x=4
divide by 2 on both sides:
x=2
So the answer to the problem is A

Answer 2

If this involves variables, then your equation can be

m times 2 + 3 = 7

M would be 2
