Without values for the other variables, I assume you're asking for a literal equation.
12y+d=-19y+t
31y+d=t
31y=-d+t
y=(-d+t)/31
I think its 4 because the lines intersect 4 times but its been too long since ive done nonlinear equations
Answer:
w = -15
Step-by-step explanation:
-5w = 7 - 4w + 8
Grouping like terms together,
-5w+4w = 7+8
-w = 15
w = -15
1020 + 1020 = 2040
%60 of 1020 is:612
2040+612=2652
so third one is true
