What is the solution to the system of equations below 2x - y = 10 and y=1/2 x+5​

(10, 10 )

Step-by-step explanation:

Given the 2 equations

2x - y = 10 → (1)

y = x + 5 → (2)

Substitute y = x + 5 into (1)

2x - ( x + 5) = 10 ← distribute parenthesis on left side by - 1

2x - x - 5 = 10

x - 5 = 10 ( add 5 to both sides )

x = 15 ( multiply both sides by 2 to clear the fraction )

3x = 30 ( divide both sides by 3 )

x = 10

Substitute x = 10 into (2) and evaluate for y

y = (10) + 5 = 5 + 5 = 10

solution is (10, 10 )

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
