Answer:
x = 3, y = 19
Step-by-step explanation:
x = 3, y = 4x + 7
Substitute x =3 into the second equation
y =4*3+7
y = 12 +7
y = 19
x = 3, y = 19
Answer:
12
Step-by-step explanation:
write it out:
3/7 x x/28
cross-multiply and solve:
3*28 and 7x
3 x 28 = 84
make an expression:
84 = 7x
solve the expression:
7x/7 = 1
84/7 = 12
x =12
