9(p - 4) = -18
Simplify our equation by multiplying the parenthesis out.
(9 × p) + (9 × -4) = -18
Simplify.
9p + (-36) = -18
Get rid of parenthesis.
9p - 36 = -18
Now, since we're trying to isolate "p," we need to add 36 to both sides.
9p - 36 + 36 = -18 + 36
Simplify.
9p = 18
Divide both sides by 9.
9p ÷ 9 = 18 ÷ 9
Simplify.
p = 2
~Hope I helped! :)~
Either add or multiply I think
a is the best way to find it if there is points involved so keep that in mind
The answerer is combining terms in x with constants
that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms
= 31x + 0.5 ← correct simplification
Answer:
x = 13
Step-by-step explanation:
In a triangle, all the angles equal 180 so
2x + 5x - 7 + 6x + 18 = 180
combine like terms
13x + 11 = 180
13x = 169
x = 13
