Answer:
- D
- B
Step-by-step explanation:
You may find this easier if you distribute the minus sign first.
<h3>1)</h3>
2a^2 -3ab +5b^2 -a^2 +2ab -3b^2
= (2 -1)a^2 +(-3+2)ab +(5 -3)b^2
= a^2 -ab +2b^2 . . . . . matches choice D
__
<h3>2)</h3>
6x -3 -2x +2
= (6 -2)x +(-3 +2)
= 4x -1 . . . . . matches choice B
The bottom one is correct.
Answer:
Given Equation: 5x/10 = 2.
Steps:
Step 1: Multiply both sides of the equation by the L.C.M of the numerators of both sides of the equation ( 10 and 1). L.C.M is 10
(5x/10).10 = 2x10
5x = 20
Step 2: Divide both sides by the co-efficient of x i.e.5
(5x)/5 = 20/5
x = 4
