\u27a1\ufe0f Solve for b.<\/strong><\/p>\n\n\n\n

11b \u2212 2b = 9<\/p>\n\n\n\n

b =______<\/p>\n<\/div><\/div>\n\n\n\n

Combine the b terms:<\/p>\n\n\n\n

11b \u2212 2b = 9
9b = 9<\/p>\n\n\n\n

Divide by 9 to solve for b<\/em>:<\/p>\n\n\n\n

9b\/9 = 9\/9<\/p>\n\n\n\n

b = 1<\/p>\n\n\n\n

m + 6m = 7<\/p>\n\n\n\n

m =_______<\/p>\n<\/div><\/div>\n\n\n\n

m is the same as 1m.<\/p>\n\n\n\n

Combine the m terms:<\/p>\n\n\n\n

m + 6m = 7
7m = 7<\/p>\n\n\n\n

Divide by 7 to solve for m:<\/p>\n\n\n\n

7m\/7 = 7\/7<\/p>\n\n\n\n
