What is the solution to this equation 3x-7+4x x28

568

Step-by-step explanation:

First, since x is 5, we sub in 5 for each x. So the equation now looks like 15 - 7 + 20 times 28. So we want to do 20 times 28 first. This equals 560. So 15 minus 7 is 8 and 8 plus 560 is 568. I hope this helps! Please make me brainliest!

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
