2y+x-2y+3x=180
x=45
2x-15=-2y+3x
y=30
Answer:
"t" is not a specific thing, this is just the sign of your variable.
t = 4 × 2.5
t = 10
X=22 because if y=6 and x=10 so 6+4=10 so 18+4=22
Answer:
1/2(2x-6)= -6
Step-by-step explanation:
Multiply the two sides by the equation 2
2x-6=12
move the constant to the right hand side change sign
2x = -12 + 6
calculate the sum
2x= -6
Divide the 2 sides by 2
x= -3
