Question

help please

Answer 1

Using the equation: 7x – 3 = 2x + 12, check at least three different values for x, showing all work. Tell whether each value you chose is a solution.

Answer 2

Start by getting the x's on one side of the equation to find the actual solution

Answer 3

ok so...18x?

Answer 4

Go step by step. First add 3 to both sides

Answer 5

ok so 7 and 17.

Answer 6

7x – 3 = 2x + 12
+ 3 + 3

Answer 16

no? not right?

Answer 17

Not right. You can't just add 2x and 15. Think of them as shapes. x's are squares and numbers are triangles

You can only add?/subtract the same shape

im lost=.= I don't know how to do this:/

Answer 19

You can only add and subtract squares
