i think this is right i hope it helped :)
Step-by-step explanation:
5m - 8 = 2m + 1
5m + 2m - 8 = 1
7m - 8 = 1
7m = 7
m = 1

Answer:
Step(iii)
The value of 'f' = 3
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given - 12 = 4(f-6)
Multiply
- 12 = 4 f - 24
<u><em>Step(ii):-</em></u>
- 12 = 4 f - 24
Adding '12' on both sides, we get
- 12 + 12 = 4 f - 24 + 12
0 = 4 f - 12
4f - 12 =0
4 f = 12
<u><em>Step(iii):</em></u>-
Dividing '4' on both sides, we get
f = 3
Answer:
(1, 4 )
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 4x → (2)
Substitute y = 4x into (1)
4x = x + 3 ( subtract x from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4x = 4 × 1 = 4
Solution is (1, 4 )
