Question

The sum of two numbers is 11. The larger number is 1 less than twice the smaller number. What are the two numbers?

Which equations can be used to express the problem as a system of two linear equations in slope-intercept form? Select all that apply.
y = one-half x minus 1
y = 2x –1
y = x –11
y = x + 11
y = 11 – x

Answer 1

Answer:

let the smaller no be X

then,

the greater no be 2x-1

hence,

adding the both numbers,we get,

X+2x-1=11

X=4

Answer 2

Answer:

we can use : y= 2x-1 & y= 11-x

Step-by-step explanation:

if , y =2x-1 & y=11-x ,

then : 2x-1 = 11-x

3x = 12

x = 12/3 =4

x = 4

• y = 2×4 - 1 =8-1 =7

then small number = 4

and large number = 7
