Answer: 3x - 23
Step-by-step explanation:
To solve the equation goes thus:
= 2(x-7)+x-9.
We have to open the bracket first
= 2x - 14 + x - 9
We then collect like terms
= 2x + x - 14 - 9
= 3x - 23
Therefore, the answer is 3x - 23
Answer:
1(left) goes with 1
2(left) goes with 3
3(left) goes with 2
4(left) goes with 4
Step-by-step explanation:
2(5+6) = 22
3(5+3) = 24
2(4+5) = 18
2(3+2) = 10
10 + 12 = 22
8+ 10 = 18
15 + 9 = 24
6 + 4 = 10
1(left) goes with 1
2(left) goes with 3
3(left) goes with 2
4(left) goes with 4
