The variable in equations are always the letters so the variable in this equation is y
Answer:
39.75
Step-by-step explanation:
so first we do 50-11.50-3.75+5. to simplify it 55-15.25
if u do the math that equals 39.75
to double check 39.75+15.25=55
5. the first equation gives you the value of y. So plug in the value of y into the second equation:
3x+2(-x-7)=3.
Simplify: 3x-2x-14=3.
Subtract: 1x-14=3.
Add 14 to both sides: x=17.
Now you know the x value.
You plug in the x value into the first equation: y=-17-7
Solve: y=-24
Answer: 17, -24
Answer: Y=8
Step-by-step explanation:
considering you are solving for Y and 4/2 is a fraction you would solve the equation like so:
Y - 4/2 = 10
Y - 2 = 10
you then add 2 to both sides of the equation and cancel it out from the left side leaving only Y.
Y = 8
