6a - 2b + 7a - 4b + 2​

13a + -2b + 2

Step-by-step explanation:

Add the numbers with the variable of A up, 6a+7a=13a

Add the numbers with the variable of B up, 2b-4b=-2b

Then there is only the number 2 left,

And other variables with different numbers cannot add up

Thus it is ended with 13a+-2b+2

c-4 is the final answer! : )

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
