Answer: x = 20
Step-by-step explanation:
Let x represent the number
9x - 4 = 176
9x = 180
x = 20
checking our answer
9*20-4 = 180- 4 = 176
Answer:
42%

just makes sence I think
Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
Answer:
S= 5, L= 12
Step-by-step explanation:
To find the value of L and S, we need to first label the 2 equations.
L +S= 17 -----(1)
3L +2S= 46 -----(2)
From (1):
L= 17 -S -----(3) <em>(</em><em>-S</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
Subst. (3) into (2):
3(17-S) +2S= 46
3(17) -3S +2S= 46 <em> </em><em>(</em><em>expand</em><em>)</em>
51 -S= 46
-S= 46 -51 <em>(</em><em>-51</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
-S= -5
S= 5 <em>(</em><em>divide</em><em> </em><em>by</em><em> </em><em>-1</em><em> </em><em>throughout</em><em>)</em>
Subst. S=5 into (3):
L= 17 -5
L= 12
