Answer:
x = 6
y = 18
Step-by-step explanation:
Equations : x + y =4x & 2y - x = 30
Rearrange:
y = 3x & x = 2y - 30
Substitute
y = 3(2y-30)
y = 6y - 90
5y = 90
y = 18
x = 2y-30 = 2*18-30 = 6

Answer:
1.2 x 102
Step-by-step explanation:
An integer is an whole number. It is not a fraction or a decimal.
Types of Integers
1. Positive integers e.g. 18, 3, 149
2. Negative integers e.g. -30
3. Zero integers e.g. 0
1.2 x 102 = 122.4. 122.4 is not an integer because it is not a whole number
