Step-by-step explanation:
step 1. 4x + 27 + 3x = 90 (definition of a rectangle)
step 2. 7x = 63 (collect like terms. subtract 27 from both sides)
step 3. x = 9 (divide both sides by 7)
It would be 4
5 - (- 1)
Would just be 5 - 1 which is 4
I’m afraid you can’t delete , unless if we report it or else there’s no other way
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
Answer: -5 and 2
Because it equals 3 when added.
And -10 when multiplied.
