Answer:
Step-by-step explanation:
13x + 47 = 151
subtract 47 from both sides
13x = 104
divide by 13 on both sides
x = 8
inverse operation = x=.5
simplify = x=1/2
inverse operation = x=.5
solution = x=1/2
check:
Let x = 3/2
10×3/2-5=10
use this rule = a×b/c=ab/c
10×3/2-5=10
Simplify 10×3 to 30.
30/2-5=10
Simplify 30/2 to 15
15-5=10
Simplify 15-5=10
10=10
Checked✅
Answer:
1 Add 88 to both sides.
2x=10+8
2x=10+8
2 Simplify 10+810+8 to 1818.
2x=18
2x=18
3 Divide both sides by 22.
x=\frac{18}{2}
x=
2
18
4 Simplify \frac{18}{2}
2
18
to 99.
x=9
x=9
Step-by-step explanation:
2x−8=10
1 Let x=9x=9.
2\times 9-8=10
2×9−8=10
2 Simplify 2\times 92×9 to 1818.
18-8=10
18−8=10
3 Simplify 18-818−8 to 1010.
10=10
10=10
1.84 * 10^-6
Hope this helpsss
