Steps:

Step 1: Simplify both sides of the equation.

4x+3=9

Step 2: Subtract 3 from both sides.

4x+3−3=9−3

4x=6

Step 3: Divide both sides by 4.

4x /4 = 6 /4

Answer: x= 3/2

Answer: (-20,-4)

First, you substitute y into the first equation to get 0.01x - 0.3(0.1x - 2) = 1

You then distribute the 0.3 to what is inside the parentheses to get 0.01x-0.03x+0.6=1
(Note: the 0.6 is positive because two negatives multiplied equal a positive)

Now you combine like terms to get -0.02x+0.6=1

Subtract 0.6 from both sides of the equal sign to get -0.02x=0.4

Divide each side by -0.02 to get x=-20

Now plug in -20 to y=0.1x-2 to get y=-4

This gives you the answer (-20,-4)

Step-by-step explanation:

T0 = a³+4

T1 = a⁴x a¹ +4

T2= a³ + a³ + 4

T3= a⁴ + a⁴* a² + 4

T4= a⁴ + a⁴ x a¹ + 4

T5= a³ + a³ + a⁴+4
