Question

a) 2(2x - 2.2) = 4.6
b) 3(2y + 3) = 4y + 3​

Answer 1

Step-by-step explanation:

a) Let's solve your equation step-by-step.

2(2x−2.2)=4.6

Step 1: Simplify both sides of the equation.

2(2x−2.2)=4.6

(2)(2x)+(2)(−2.2)=4.6(Distribute)

4x+−4.4=4.6

4x−4.4=4.6

Step 2: Add 4.4 to both sides.

4x−4.4+4.4=4.6+4.4

4x=9

Step 3: Divide both sides by 4.

4x/4=9/4

x=9/4

b) Let's solve your equation step-by-step.

3(2y+3)=4y+3

Step 1: Simplify both sides of the equation.

3(2y+3)=4y+3

(3)(2y)+(3)(3)=4y+3(Distribute)

6y+9=4y+3

Step 2: Subtract 4y from both sides.

6y+9−4y=4y+3−4y

2y+9=3

Step 3: Subtract 9 from both sides.

2y+9−9=3−9

2y=−6

Step 4: Divide both sides by 2.

2y/2=-6/2

y=−3

Answer 2

Answer:

a) 4x-4.4=4.6

4x=9

x=2 . 25

Step-by-step explanation:

b) 6y+9=4y+3

2y=-6

y= -3
