I hope this helps
the brackets can represent multiplication or group large
for example
5 × 4 + 7 × 9
(5 × 4) + (7 × 9)
20 + 63
= 83
or
73 + 92 + 54 + 96 × 6
(73 + 92) + (54 + 96) × 6
165 + 150 × 6
315 × 6
= 1890
Answer:
5x=1
Step-by-step explanation:
it just comes easy to me
21x -15 + 5 = 10x - 5
21x -5 = 10x
11x = 5
x = 5/11
Answer:
x = -5/2
Step-by-step explanation:
4x+2 = -8
We are solving for x
The first step in isolating x is to subtract 2 from each side
4x+2-2 = -8-2
4x = -10
Divide each side by 4
4x/4 = -10/4
x = -10/4
Simplify the fraction
x = -5/2
Answer:
h=5
Step-by-step explanation:
18x2 = 36
36/6 = 6
6 = h+1
h=5
Check:
5+1 = 6
6x6 = 36
36/2 = 18
