Solve the system of equations

x = -2 and y = -21

Step-by-step explanation:

Given equations are :

From equation (1) and (2)

Put the value of x in equation (1)

y = 15(-2) + 9

= -30 + 9

y = -21

So, the solution of the equations are (-2,-21).

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
