2x plus 5x simplified is 7x.
In math evaluating is where you simplify an expression as much as possible. For example to evaluate 5+2 you simplify it so it is 7. To evaluate 5x+3x+4y you simplify it to 8x+4y.
If x = -7 and y = -3 then 5(-7) -2(-3) = -29
3x = 5x - 10 Subtract both sides by 5x 3x - 5x = 5x - 10 - 5x Simplify - 2x = - 10 Divided both sides by -2 to isolate x - 2x / - 2 = - 10 / - 2 Simplify x = 5 Plug x into the original equation. 3(5) = 5(5) - 10 = ? Simplify 15 = 25 - 10 = ? Simplify 15 = 15 = ? Therefore 3x = 5x - 10 = 15
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
