Answer:
Step-by-step explanation:
-10
Answer:
x=25/23
Step-by-step explanation:
Let's solve your equation step-by-step.
−23x+37=12
Step 1: Subtract 37 from both sides.
−23x+37−37=12−37
−23x=−25
Step 2: Divide both sides by -23.
x=25/23
Answer:
x=1 and y=7
Step-by-step explanation:
7x−2y=−7;y=7
Rewrite equations:
y=7;7x−2y=−7
Step: Solve y = 7 for y:
y=7
Steps: Substitute 7 for y in 7x−2y=−7:
7x−2y=−7
7x+(−2)(7)=−7
7x−14=−7 (Simplify both sides of the equation)
7x−14+14=−7+14 (Add 14 to both sides)
7x=7
7x/7 = 7/7 (Divide both sides by 7)
x = 1
So the answer is, x=1 and y=7
