Answer:
x = 
or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)

Answer:
x≥2
Step-by-step explanation:
Let's solve your inequality step-by-step.
12−7x≤−2
Step 1: Simplify both sides of the inequality.
−7x+12≤−2
Step 2: Subtract 12 from both sides.
−7x+12−12≤−2−12
−7x≤−14
Step 3: Divide both sides by -7.
−7x/−7 ≤ −14/−7
x≥2
