=0.5*10*4
=20
Answer:
1 2⋅−1⋅3 5=4 5
Step-by-step explanation:
Combine multiplied terms into a single fraction
12y−1⋅35=45
\frac{1}{2}y-1 \cdot \frac{3}{5}=\frac{4}{5}
21y−1⋅53=54
12−1⋅35=45
(-1, 0)
Start by adding -2x to both sides of the second equation. Then substitute that equation into the first.
3x+3(2x+2)=-3
Solve the equation for x.
When you've found the value of x, substitute that value into the equation with the isolated y.
y=2(-1)+2
