x^2+4-5

Step-by-step explanation:

the first box multiply the next box

x^2-1x+5x-5

x^2+4x-5

Hi! Let's get solving. :D

Okay.. This is a double bracket, so use the '' Waves '' method to expand the bracket. I don't mean to be lazy, but it's kinda hard to explain the working here, so here's a brilliant video that explains this method:

X^2+4−5

Stay safe! :)

Note: I'm not a maths expert, please double check your answer.

Subtract 3 from both sides

-18 - 3 = x/3

Simplify -18 - 3 to -21

-21 = x/3

Multiply both sides by 3

-21 * 3 = x

Simplify -21 * 3 to -63

-63 = x

Switch sides

x = -63
