Answer:
(- 1, 1 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = x + 2 → (2)
Substitute y = 3x + 4 into (2)
3x + 4 = x + 2 ( subtract x from both sides )
2x + 4 = 2 ( subtract 4 from both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
Substitute x = - 1 into either of the 2 equations and evaluate for y
Substituting x = - 1 into (2)
y = - 1 + 2 = 1
Solution is (- 1, 1 )
Answer:
4/16 because 5/20 is equivalent to 1/4. 4/16 is also equivalent to 1/4
Step-by-step explanation:
Divide 5/20= 1/4
Multiply 4 times the numerator and the denominator:
4 × 1 = 4
4 × 4 = 16
so we know 4/16 is equivalent to 5/20
